ROCKBROSBike Tail Light Smart,Brake Sensing Bicycle Rear Lights for Night Ride,Ultra Bright LED Back Lights,Type C USB Rechargeable,IPX6 Waterproof,Cycling Safety Taillight Accessories

This is the best taillight I’ve come across. It’s made of metal-not plastic. It screws securely to the rods under the bike seat or it will “bungee” to the seat tube. The light itself unscrews to recharge and seems to hold a charge for a good amount of time. It offers a variety of blink settings. I particularly like the charge level indicator- four tiny blue lights around the center of the lens that go out one at a time as the level decreases. It is very bright and easily seen in daylight. I would buy this light again.

The media could not be loaded. The smart brake sensing feature is legit - it actually brightens when I slow down or stop, just like a car brake light. That extra visibility gives me more confidence when riding on roads, especially at night or in low-light conditions. Drivers definitely notice me more now.The light is USB-C rechargeable, which is super convenient (finally no more micro-USB cables), and the battery life has been solid so far. I’ve done several multi-hour rides without needing a recharge.I attached a short video that shows the different light modes so you can see how it works in action. In the video, it’s hard to see, but there are 4 tiny blue LEDs that flash from time to time — these are the battery level indicators. Each dot represents 25% battery life, so when all four are flashing, it means the light is fully charged. A small but really useful feature!It’s also proven to be durable. I’ve ridden through rain and puddles, and the IPX6 waterproofing has held up perfectly.Overall, this is a bright, smart, and well-designed rear light. If you ride on streets or trails and want to boost your visibility and safety, this one’s absolutely worth picking up. I do wish it were a bit cheaper, though.

Nice little light. I've been wanting a under seat rear light for awhile and this fits the bill: compact, usb-c charging, reasonable price. A few wishes for the future: hope they make a brighter version and I hope it lasts for a least a couple of year. Highly recommended

I was pleasantly surprised by this product. It's incredibly aero and sleek - with no extra space taken. It can actually be mounted upside down from how it's shown in the product photos to make it even more aero and sleek - essentially hugging the bottom of the seat. It seems to work well. I can't speak to the brake light function, as it's very hard for me to watch my own tail- but it seems to work well otherwise.

This is a review after owning the lamp for 1 year.It's held up well to all weather conditions and still performs like new.I did put a little anti-seize on the threads because it's made from aluminum. However I don't see any corrosion after a year.I like the auto brake light, and auto-off function.It's small and was very easy to install.If there was one thing I would change it would be to change the screw-fit to a bayonet fitting. This would speed up taking it off and on for charging.

Works well on bike; easy to set up;Different lighting levels and modes for different weather and day conditions for your rideAfter changing long running until rechargeA must have for safety on your bike

Mantiene la calidad que la marca nos ofrece ,buen ajuste ,súper estable en los descensos ,y lo más importante la visibilidad que da es muy buena

Just got my really cool Rock Bros rear led bike light for my ActBest e-bike. Each led light mode has three settings low, med & high for fast flash, breathing fade in and out, and steady on. Also this light has a motion sensor inside so when stop the rear light brightens up. After that it continues the light mode. This is the original model, there’s two other ones with a different name but with a cheaper price.
